The Lauren fashion dynasty is preparing for this weekend’s lavish wedding of Dylan Lauren and hedge-fund manager Paul Arrouet. Sources tell us the guest list for Saturday’s event at the family estate in upstate Bedford has been kept “small and intimate.” The Dylan’s Candy Bar founder recently told us, “I want it to be extra creative and extra special.” Ralph Lauren has designed his daughter’s dress, which is of course being kept strictly under wraps. Dylan’s brother, David, is also set to marry Lauren Bush, but the couple haven’t yet confirmed a date or location.
